All these diffinitions are incorrect really, The band 'The butthole surfers' actually used this as their name because of all the things people would associate with it. What it actually means is when someone is running along and fall on their ass and slide on the grass. That is butthole surfing.

I love butthole surfers they own. Yas are all rpobably gunna gimme thumbs down but Its true!

The Butthole Surfers are a great band from Texas. They formed in 1981 and were fronted by Gibby Haynes. Their genre is hard to define, but it's a strange, yet great, mix of avant-garde, hardcore, and psychedelia. Everyone should listen to them.

The Butthole Surfers were a major influence on Kurt Cobain.
